Question

Evaluate \dfrac{e}{4}+2f-3 4 e ​ +2f−3 when e=12e=12 and f=\dfrac12f= 2 1 ​ .

Answer 1

it equals 1 :)

Explanation:

Answer 2

Answer: -406

Explanation:

We have the following expression:

`(e)/(4)+2f-34e+2f-3`

In addition we know:

`e=12` and
`f=(1)/(2)`

If we substitute this in the expresion, we will have:

`(12)/(4)+2((1)/(2))-34(12)+2((1)/(2))-3=-406`
